Ards and North Down Borough Council has now passed a motion calling for new legislation to tackle the sale of legal highs and will now write to the Home Secretary to ask that new laws are introduced as quickly as possible.

The council has also asked officials to examine whether action can be taken against people who sell legal highs - similar to that taken by Belfast City Council last year.
